AI Security Review
scanned 5d ago · by lpm-firewall-aiThe bundle sends the embedding hostname and RunFrame activity metadata to its PostHog host by default, with only a global opt-out visible in the source. This is suspicious runtime telemetry; the flagged registry token flow is part of explicit sign-in to the package’s own service.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Importing the browser bundle initializes PostHog unless telemetry is disabled; activity events are sent when the RunFrame activity hook runs.
Impact
The analytics service can associate RunFrame activity with the hostname embedding the component.
Mechanism
The bundle derives an identity from the referrer or current hostname, then includes the embed domain and activity properties in PostHog events.
AI rationale
The bundle sends the embedding hostname and RunFrame activity metadata to its PostHog host by default, with only a global opt-out visible in the source. This is suspicious runtime telemetry; the flagged registry token flow is part of explicit sign-in to the package’s own service.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The browser bundle initializes PostHog telemetry by default, with a global opt-out flag.
- Telemetry identifies non-local embeds using the referring or current hostname and sends that domain with activity events.
- The activity hook sends component, embed status, active tab, and source metadata when those properties change.
Evidence against
- The registry token flow is tied to a sign-in handler and sends its login token to the tscircuit registry.
- The telemetry uses the package’s PostHog host and includes an opt-out setting; no credential exfiltration was identified.
